FIELD: information technologies.
SUBSTANCE: method contains the following stages: on transmitting side they download orthogonal codes in lines from a number of multiuser communication lines, signals are sent as loaded with these codes, which correspond to lines, on receiving side they receive information on vector of transient noise according to vector of actually received signal, and quantitative value of transient noise is identified on the side of a certain line out of mentioned lines. System contains transmitting device, which sends test signals loaded with orthogonal codes, and receiving device, which receives test signals and calculates quantitative value of transient noise.
EFFECT: detection of transient noise among multiple lines for optimisation of lines operation.
